Fuji Apple
Very sweet, crisp, dense fruit with good keeping quality when harvested and stored correctly. Late season; needs adequate autumn warmth to mature. Tree size, anchorage and drought response depend strongly on the grafted rootstock; full sun, drainage, compatible pollination and annual crop management are essential.
Profile
- Fruit
- Very sweet, crisp, dense fruit with good keeping quality when harvested and stored correctly.
- Harvest
- Late season; needs adequate autumn warmth to mature. Timing shifts with region and weather.
- Cultivar distinction
- Ralls Janet × Delicious parentage; many color strains exist.
- Pollination
- Plant a compatible cultivar with overlapping bloom; bees transfer pollen.
Water & soil targets
- Moisture (VWC)
- Site-calibrated; varies by soil and rootstock
- Salinity tolerance
- Sensitive to saline irrigation; rootstock affects response, but salt accumulation can reduce growth and fruit quality.
- Drought tolerance
- Limited to moderate; fruiting and dwarf-rootstock trees need reliable moisture.
Optimal root measurement depth
8–18 in
Most absorbing tree roots live in the upper 12–18 inches, out toward the drip line. Typical guidance; confirm with a soil probe on site.
Keep moisture reasonably even through its long fruit-development period; reduce irrigation with weather and soil conditions, not red skin color alone. Wet the active root zone, keep the graft union and trunk base clear, and let drainage restore aeration between irrigations.
Problems to watch
- Alternate bearing following heavy crops
- Codling moth or locally important fruit insects
- Fire blight, apple scab or cankers according to local pressure
Stress signs
- Persistent leaf wilting or marginal scorch
- Reduced shoot extension and undersized fruit
- Premature leaf or fruit drop
Where you'll find it
- Fresh fruit
- Stored dessert apples
